The Horrifying Philosophy of the Borg

In 1989, Star Trek: The Next Generation introduced us to the Borg, a collective of cyborgs that work together as one unit to capture and assimilate the universe's beings and technology for their own purpose- which is to capture and assimilate others. They are seemingly soulless, more powerful than Starfleet, and growing bigger and more powerful all the time. A truly frightening nemesis. 

The more our heroes learn about the Borg, the more frightening they became. In later episodes, the philosophical question of individualism, free will, and the hive mind are explored. However, over time and multiple appearances in later movies and series of the Star Trek universe, the Borg lost their horror because they were always ultimately thwarted. We also got to know a few individual Borg drones, and they became sympathetic. The Borg never succeeded in permanently assimilating any of the main characters, although they came frighteningly close.
